Police in Boston say a large group of people took over a city street very early on Sunday morning and attacked officers attempting to disperse the crowd.

BPD Commissioner Michael Cox said that officers responded to the area of Mass Ave. and Tremont Street around 2 a.m. to a report of a “large group of people” engaged in illegal street racing.

“As officers approached the scene, they were met by a pretty large group of people and some of the individuals in the group started to throw cones, poles, and other objects at the officers,” Cox said.

As the police exited their car in an attempt to arrest some of the participants, the violence continued, according to Cox. The officers were assaulted, and a crusier set ablaze.

“One vehicle was damaged in a fire and was totaled,” Cox said. No police were injured, he said.

Two people were arrested at the scene.

This is a developing story.
